New energy vehicles have automatic transmissions, and new energy vehicles are basically dominated by automatic transmissions. The structure of new energy vehicles is different from that of fuel vehicles. According to the structure of the model, taking pure electric vehicles of new energy vehicles as an example, pure electric vehicles use three electric vehicles as the power generation source of the vehicle, and the structural power has no gearbox or other things. The working principle of electric vehicles, according to the power generation method of the vehicle when it is working, the pure electric vehicle provides electrical energy to the motor through the battery, and drives the motor to run, thereby driving the vehicle.
According to the structural characteristics of the drive motor, when the motor is working, its current controls its own speed range and torque output, and can fully adapt to all speed ranges under current and voltage conditions. That is, its own acceleration and deceleration does not rely on the gearbox to convert power, so from this point of view, the speed conversion can be achieved in the vehicle gearbox without manual physical intervention. Pure electric new energy vehicles only have automatic transmissions.
Therefore, the current new energy vehicles are generally not equipped with multi-speed gearboxes. Due to the torque output characteristics of the motor, it does not require devices such as “gearboxes” to coordinate the relationship between speed and torque.
